Advice needed

Lately I’ve been wanting to explore in terms of my sexuality. I’m in a relationship rn ( going on 6 yrs) and I’ve spoken to my bf about this. I’ve always been attracted to females but like never acted on it? I’m also horribly shy lol I don’t want a threesome but I wouldn’t mind my man watching ??? Good idea/bad? I’m confused lol

For those asking: I’m 20. Also I do see the concern about jealousy and the feeling of seeing my bf with someone else. I’m seeing this from a thrill side not so much a serious thing. If anything happens I will update!
